TO ALL WIIOM IT MAY CONCERN: I Y

Be it known that I, ROBERT GRANT, of the city of Brooklyn, in the county of Kings, and State of New York, have invented certain new and useful Improvements in Apparatus for Making Portable Compressed or Condensed Carbonio Acid Gas, or other gases for manufacturing soda-water, or for other purposes of impregnating iluids with carbonio` acid gas or other gases; and I hereby declare thc following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, which are lettered to correspond with and form a part ofthe spccication. I

In order that the'publicinay fullyunderstand the nature of my invention, and those skilled in the mechanic varts be enabled to construct and use the same, I will describe it as follows, to wit:

Figure 1 is a perspective drawing of. my apparatus. Letter A is the compressed-gas cylinder; B is the water-tank; C is the gas-regulator; D is the ice-box, or refrigerating-ch'amber; E is a mercury-gauge; F is the eduction-pipe from the Vwater-tank to the gas-injector, I), iig. 2; Nisthe gas-injecting chamber; O is the induction-,water pump; It is the equalizingpipefrom the regulator to the water-tank; S is the draught-cock; T is the pipe connecting the compressing-cylinder A with the regulator C; M is the induction-water pipe; W is the Water-gauge; X is the cock that controls the low of the'gas fr'om the regulator to the injector I); Z is the stop-cock controlling theflow of'gas from the regulator to the water-tank.

Figure 2 is avertical section ofthe gas-injecting chamber N, showing the injector-gas jet P and the waterregurgitating valve V. A

Figure 3 is a perspective sectional drawing of the gas-regulator C. 2 is the gas-regnrgitating valve; 3 is the gas-regulating-screw valve; 8 is the gas-induction orifice; 9 is the stem of the air-tight plunger', which is operated by means of a spiral spr'ng and thepressure of the gas, and which operates the screw-valve Shy means ofthe toggle-joint G.

Figure 4. Letter D is the ice-box or refrigeratingchamber containing the mixing-coil and cooler.

Figure 5 is a vertical section of the water-tank B, showing the horizontal shaft 1, and crank 2, stuiingd boxes 3 3', and the revolving niixing-fzns 4 4. 4 secured. to a gland, 5,'tho same being secured to the shaft 1 by means oi'a set-screw G. The top of the tank 13 is secured,by lugs and screws for fastening the same, to the body of the tank with a suitable packing. This tank may belined with tin or any other non-oxidizing material. 7 is an exhaust-cock for exhausting the air from the water-chamber when the apparatus is put in action.

Ilford@ of Operating the Apparatus.

First fill the portable cylinder A with compressed or condensed gas, under an atmospheric pressure of from four hundred and iift'y to six hundred pounds to the square inch; then attach the cylinder to the regulator C,

by means of the coupling T, (seeiig. 1;) then turn on the full pressure of gais from the cylinder A to the regulator C, through the induction-pipe, by means ofthe stop-cock G,fig. 1, theregulator being graduated niriet-y pounds pressure to the square inch, through the education-pipe, bymeans oi' the air-tight plunger and spiral spring operating upon the screw-valve 3, by the toggle-joint 6, iig. 3, which is actuated by the pressure of the gas in the regulator; then ll the Watentank B, lig. 1, with water, by means of the pump o, letting oi the air through the exhaust-cock 7, iig. 3; thcnturn on the pressure ofthe gas from the regulator tothe Water-tank, bymeans of the stop-cock, at the same time revolving the fans 1 4 et, by means of the crank 2, iig. 5, for the purpose of effecting a partial absorption ofthe super-induced gas, by the Water in the tank B. This rotationI continue at intervals. As the fresh water is pumped into the tank again, I turn the pressure of the gas from tho regu lator to the injector Gr, tig. 2, by means ofthe stop-cock X, gs. l and 2. i

When Iwish to draw soda-water7 I open the draught-cook S, fig. 4'. That allows the water to how through the mixing-coil, under a pressure of ninety pounds to the square inch, from the water-tank B. As this water passes the injector I), g. 2, the gas minglcs intimately with thcwater through lthe jet P, under a pressure. As the water and gas pass through the mixing-coil, the combination becomes complete by the final absorption of the gas by the water. Y

Ido not confine myself` to the above arrangement alone, from the fact that it maybe found necessary to use the individual parts, or'moditications thereof, separately,'and otherwise adapted for similar purposes, to suit the time and'exigencies ofthe situation.

I am aware that water has been pumped, against the pressure of gss,'in sodafountains, which gas remainsv inthe fountain after the soda-water has been drawn oli', preparatory to refilling the fountain with waterfor the purpose of again manufacturing gas, and compressing the same to form the full equivalent of soda-water. This was done for the purpose of saving the residuur'n of gas in the fountain after the soda-water was drawn olf. But by my improved process I effect a continuous manufacture of soda-water, under the equivalent automatic pressure of gas, never allowing the fountain to become exhausted, nor requiring n. separate process of/ manufacturing and refilling the fountain with gas and water after the soda-water was exhausted.

In effecting the process of filling the water-tank B with Water, I do not confine myself to the pump o, lig. 1, as the same result can be produced by means of a reservo-ir of water, placed at a suiiicient elevation, and connecting with the water-induction pipe m., g. 1. Also in this case, not only the pumpfbut likewise the water-teni: B itself, may be dispensed with', if desirable, by simply connecting the induction-water pipe m immediately to the water-pipe F, l, the compressing of the gas with the water taking place sufficiently well at the juncturc of the gas-injector I, and'in the mixing-coil the flow of the gas being controlled by the stopeock X.

The nature of my invention consists in the use of detachable cylinders, of compressed or condensed gas or gases, operating a mixer or injector, wherein gases are combined with Water, n any locality, thus avoiding the necessity of transporting the water for the purpose of makingmineral or eervescing fluids for drinking or other purposes; also for the purpose of avoiding the cemmingling of the gas or gases and Water in the compressingcylinder A, thereby obviating the oxidi-zation of the interior of thecylinder A, and rendering itl unnecessary to line said cylinder with any unoxidizing substance, as the dry .gas does not affect the metal thereof, thus rendering the transportable cylinders compact, light, strong, and cheaply. constructed for use.

Therefore, what I claim as novel and useful; and what I wish to secure` by'Letters Patent of the United States, is

1. The cylinder A, regulator C, injector P, water-tank B, and regurgitating-valves 2 and 3, arranged und operated as described, and'shown in the drawings, or otherwise modified for the purpose set forth.

2. I claim the continuousautomatic process of compressing carbonio acid or other gases in water by the means substantially as described, and for the purposes above set forth.

In testimony whereof, I have hereunto subscribed my name in the presence of two witnesses.

ROBERT GRANT.
